The last decades it is increasingly recognized that acute as well as chronic postoperative pain is an important problem. Treatment and prevention of postoperative pain is a challenge, especially in special patient populations where there is only limited guidance on how to optimally use opioids.

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

Without scientific knowledge, we won’t be able to tackle the grand challenges of the 21st century: climate change, energy transition, social inequality and coronavirus, for example. Professor by Special Appointment of the Social Value of Science Laurens Hessels is therefore calling for more transdisciplinary…

There are still things we can learn from the Ancient Greeks. How they managed to make sure that innovations were accepted, for example. A group of classics scholars, led by Leiden, will be carrying out research on this question funded by the largest ever NWO subsidy.

Masterclasses, network meetings and coaching cafés: the Alumni Office was offering a whole range of activities every month for the University’s alumni. Until coronavirus broke out, that is. The Leiden Alumni Webinars mean that alumni can still meet and share their knowledge with interesting speakers.…

Particularly during this time of social distancing and remote learning, it is important to carry on meeting new people – even if you don’t always feel like it after another day staring at your screen, says Wessel van Dam. In his role as assessor at the Honours Academy, Wessel represents the interests…

Native women are invisible in Mexican society. This is the conclusion Barbara Ortiz draws in her dissertation. PhD defence on 23 February.

If there’s one place at the University where it doesn’t matter where you come from, it’s De Kattekop. This, the University nursery, celebrates its 40th birthday in September. Its history reflects developments at the University. Parents are full of praise for it.

The oldest forms of literature and law originate from Mesopotamia (3000 BC until AD 70), as do important discoveries in science and technology. All these developments were recorded in cuneiform texts on clay tablets. There is still a lot to learn from the study of cuneiform texts, says Professor of…

Pieter Omtzigt, a strong contender in the polls for the Dutch general elections with his New Social Contract party (NSC), has said he would prefer to remain in parliament as party leader. He is not saying who the NSC candidate for prime minister might be and will only reveal this after the elections.…

A recent ruling by the Dutch Council of State indicates that asylum seekers may no longer be sent back to Italy. The Council of State increasingly concludes that the countries at Europe's southern and eastern external borders expose migrants to degrading treatment. This in particular is a reason for…

An international team of astronomers including Leiden scientists publishes the image of a young star with a surrounding dust disk that is still being fed from its surroundings. The phenomenon around the star SU Aur may explain why so many exoplanets are not neatly aligned with their star. The European…

Chances that Dutch Prime Minister Mark Rutte will become Secretary General of NATO are becoming increasingly likely now that the US and most western countries have expressed their support. The question now is how to appoint someone to the position of Prime Minister, who to appoint and when the situation…

Reuse everything and stop producing waste. By 2050, the Netherlands should have a circular economy. However, the new Integral Circular Economy Report by the Netherlands Environmental Assessment Agency (PBL) shows that there is still a long way to go. For the report, the Institute of Environmental Sciences…

On this page you'll find the recordings of the programme presentations held at the Leiden University Bachelor's Online Open Day of 7 October 2023. Perhaps you joined this event and would like to rewatch the presentations or are curious about ones you didn’t see the first time around. Or you haven't…

A couple of years ago, theoretical physicist Carlo Beenakker tracked down the Majorana particles and inspired Leo Kouwenhoven from TU Delft to try to create them in a superconducting nano-structure. He succeeded in doing so in 2012, and the news made headlines around the world. But a lot of work still…

Cathodic corrosion for producing nanoparticles was (re)discovered when trying to control the electrochemical etching of a scanning tunneling microscopy (STM) tip.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

The urban graveyard presents several studies in which the results of older archaeological and osteoarchaeological research are compared to more recent excavation data from several Dutch, Belgian and Danish cities and towns.

The Oral History project, as part of the Tell Balata Archaeological Park project, published an arabic-english booklet of local stories about the site of Tell Balata. An archaeological site near Nablus (West Bank).

Known technical issues that still need a definitive solution.

What does it mean to eat healthily and responsibly? This question is gaining a new urgency now that in many countries undernourishment is being overtaken by diseases of affluence, such as obesity, and we are also becoming more aware of the environmental impact of our eating habits. It’s time to take…

The central question is whether the current regime of international humanitarian law governing the conduct of hostilities in armed conflict is still adequate to deal with modern conflict scenarios, or whether it needs revision or amendment.

From the Big Bang to superconductivity. Many ground-breaking discoveries have been made in Leiden University’s long history.

In educational settings such as museums, universities and schools, white, male, able-bodied and rational subjects still dominate. Although there has been a lot of theoretical work on processes of in- and exclusion through racialization, sexualization, and disabilization, we still know very little about…

At this moment participants are still working on their trajectories. In the summer of 2024, we will have taken the final measurements and will analyse the data. We expect to present the results on this page around September 2024.

On this section of the website you can find more information about the Old Observatory and the current astronomy research institute.

Despite the fact that gold nanoparticles (GNPs) are one of the most studied nanoparticles, there is still a necessity for new approaches allowing for effective protective coating to enable wider use of GNPs in biomedical applications.

The Old Observatory is still used intensively as a university building. Yet there is still plenty to see and experience in this beautiful monument. Find out what the possibilities are here.

To study how planetary systems come into existence we study much younger systems still in formation.

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…
